Many people will have already heard about Powder Injection Moulding. Many plastic moulded products such as car bumpers are usually moulded at pressures of several atmospheres using the Powder Injection Moulding process. However Powder Impression Moulding is a new development about which few will have heard (a basic internet search on the two phrases will demonstrate this point). The advantage of Powder Impression Moulding is that it operates at essentially atmospheric pressure and hence needs much less capital expenditure than that associated with the existing injection moulding technology. There are many other advantages of the new PIM process.
